| Study group | Role | What they receive |
|---|---|---|
| Rocatinlimab | Experimental | Rocatinlimab every 4 weeks (Q4W) for 24 weeks with a loading dose at Week 2. Receives: Drug: Rocatinlimab |
| Placebo | Placebo comparator | Placebo every 4 weeks (Q4W) for 24 weeks with a loading dose at Week 2. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With a Positive Anti-tetanus Response at Week 24
Participants received 1 dose of a tetanus vaccine at Week 20. The antibody response to the tetanus vaccine was assessed by measuring serum anti-tetanus immunoglobulin G (IgG) by an immunoassay.
Measured: Week 20 to Week 24
Percentage of Participants With a Positive Anti-meningococcal Response at Week 24
Participants received 1 dose of a meningococcal vaccine at Week 20. The antibody response to the meningococcal vaccine was assessed by measuring serum anti-meningococcal IgG by an immunoassay.
Measured: Week 20 to Week 24

A Phase 3 study testing Rocatinlimab in people with Atopic Dermatitis and Moderate-to-severe Atopic Dermatitis, run by Amgen at 85 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 85 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Jul 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With a Positive Anti-tetanus Response at Week 24 (time frame: Week 20 to Week 24). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05899816, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2026.
